The Cytech H26NA0E 260W/K air-to-air heat exchanger is engineered for outdoor telecom cabinets, battery energy storage enclosures, industrial control panels, and electronic equipment cabinets that require reliable, energy-efficient, closed-loop thermal management.
Built for harsh outdoor conditions, the H26NA0E prevents dust, humidity, and airborne contaminants from entering the cabinet while maintaining stable internal temperatures, even in extreme environments ranging from –40°C to +60°C.

Product Description
260wk heat exchanger datasheet.pdf
Transfers heat using a counter-current plate heat exchanger, without mixing internal & external air.
Maintains cabinet protection while ensuring effective heat dissipation.
Ideal replacement for traditional enclosure air conditioners to reduce energy consumption.
External and internal fans feature IP55/IP65/NEMA 4/4X protection, preventing dust, water, and debris ingress.
Suitable for telecom towers, roadside cabinets, renewable energy systems, railway cabinets, and more.
Operates efficiently in –40°C to +60°C outdoor conditions.
Suitable for desert, coastal, tropical, and high-altitude installation sites.
No refrigerant or compressors → fewer failures and lower maintenance costs.
Easy installation and servicing.
External fan automatically adjusts speed based on cabinet temperature.
Reduces power consumption and noise during low heat loads.
Ensures efficient cooling when internal temperature rises.
◆Internal Circulation Fan:
Continuously draws warm air from inside the cabinet and passes it through the heat exchanger core.
◆External Ambient Fan:
Pulls outside air through the external channel to absorb heat and reject it into the environment.
◆Counter-Current Plate Heat Exchanger Core:
High-efficiency plate design
Two separated air pathways
Heat transfers through the aluminum plates
Internal airflow never contacts outdoor air, protecting sensitive electronics
As cabinet temperature increases → fan speed increases
As temperature decreases → fan slows down to save energy
This ensures:
Lower operating costs
Longer fan life
Reduced noise
Stable equipment protection
